To (1,, whom it may concern:

Be it known that l, Hnuemrr S. BLYN'r, a citizen of the United States, residing at Steubenvillc, in the county of Jefferson and State of Ohio, have invented certain new and useful improvements in Grease Compression Cups; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked. thereon, which form a part of this specification.

My invention relates to a new and novel improvement in grease-compression cups employing a gravity-weight to force the contents of the cup into the parts of the engine to be lubricated. This character of grease-cup is especially adaptable and useful on the con- 'necting-rod of an engine or any other part Where the vibration or jar is greatest, as by its peculiar construction the contents of the cup will be prevented from spilling out and the gravity-weight retained in position and kept in close contact with the body of grease contained in the cup, thus insuring an even feed of the lubricant, as will be more fully described hereinafter.

in the accompanying drawings, forming a part of this specification, T have illustrated my invention by two views, in whicl Figure 1 is a vertical sectional view of my grease-eup. Fig. 22 is a cross-sectional view of the same, taken on the line 2 2 of Fig. 1.

Numerals of reference designate like parts throughout the diiferent views, the numeral 1 being the reservoir or grease-receptacle portion of my improved cup, and 2 the neck or securing-stem, having a threaded lower portion and a channel 3, (shown by dotted lines,) communicating with the interior of the reservoir. The flow of grease through the channel 3 is regulated by a screw or plugvalve at, seated in the stem 2. Operatively seated in the reservoir is a gravity-weight 5, having a cored-out portion 6, in which are giivotally seated a pair of tumblers or eccentric friction-clutches 7 7, adapted to engage the inside wall of the reservoir, and thus prevent the upward movement of the weight 5 when the cup is subjected to a sudden jolt.

Operatively seated through a cap portion 8 is a stem 9, which passes through the weight 5, the lower end being adapted to engagethe pivotal ends of the tumblers 7 7.

Secured to the top of the cap 8 is a small supporting-column 10, having a clevis in the top, in which is pivotally secured a lever 11, one end of which is cut on a radius, acting as an eccentric, while on the opposite end is a ball or weight 12 to slightly overbalance the same. The lower end of the gravity-weight is provided with a packing-ring 13.

Vl hile the weight 5'is traveling down inside the reservoir and compressing the grease the eccentric tumblers 7 7 will be out of locking engagement with the inside wall of the reservoir; but in case of a jolt the upward movement of the weight will cause both clutches to fall and engage against the wall of the reservoir, thus locking the weight until after the jolt is passed, when the weight will again drop and the process of compression be continued. The radial cut end of the eccentric lever 11 while the weight 5 is in action compressing the grease is pushed down out of the way; but the instant the cup is subjected to a jolt the overbalanee produced by the ball or weight will cause the radial cut end to come into locking engagement with the stem 9, thus combining with the eccentric tumblers 7 7 in arresting the upward movement of said weight. As soon as the jolt has passed this lever will also assume its normal position. By this arrangement of eccentric clutches inside the weight 5 and on the outside of the cap portion l have provided a double precaution against the com: pression-weight being jolted out of its seat in the reservoir, no matter how severe or sudden the shock.

In order to remove the weight 5 from the reservoir, the cap 8 is first unscrewed, and by simply pressing down on the stem 9 the lower end of the same will engage the pivotal ends of the tumblers 7 7 and force the engaging ends upward away from the wall of the reservoir, thus permitting said weight to be lifted clear of the cup.

Having thus fully shown and described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. In a grease-compression cup of the character described, the reservoir portion having a valve-regulated outlet; a gravity compression-weight operatively seated in said reservoir; the eccentric gravity-tumblers pivotally seated in a cut-out portion of said weight and adapted to engage against the wall of said reservoir; as, and for, the purpose set forth.

2. In a grease-compression cup, of the character described, the reservoir portion having a valve-regulated outlet; a gravity compression-Weight operatively seated in said reservoir; the eccentric gravity-tumblers pivotally seated in a cut-out portion of said Weight and adapted to engage against the Wall of said reservoir; a disengaging stern operatively seated through a cap portion and through said gravity-Weight, the lower end adapted to engage the pivotal ends of the gravity-tumblers; as, and for, the purpose set forth.

3. In a grease-compression cup, of the character described, the reservoir portion having a valve-regulated outlet; a gravity compression-Weight operatively seated in said reser- HERBERT S. BLYNT. \Vitnesses:
